Block holders for AO (black) microtomes

From:

Jig1357@aol.com

Hello!
I was wondering if anyone out there who still uses the old black AO microtome
is using a clamp-type block holder. We tried one from Surgipath and it does
not seem to fit very well--the block holder has some play in it when it
should be firmly seated in the microtome. We are currently using the
Tissue-Tek block holders for which certain parts have to be replaced as they
get worn. We would like to use a clamp-type holder in which you pull the
lever forward in order to place the block in the chuck, then release the
lever to hold the block in place.
Thanks for any and all help!!
